Abstract

This experiment carried out to confirm characteristics of macrogranule (GG) for herbicidal efficacy by using remote-controlled aerial application (RCAA) to control annual and perennial weeds in rice paddy field, application methods, and application times of formulation types. Particle of 500 g GG having average diameter of 2.5~3 mm was over 85 percent, the bulk density of the particle was $0.2\sim0.4g\;mL^{-1}$ and the particle was water floating granule. Active ingredients and external form of halosulfuronmethyl+mefenacet GG remained stable under condition of storage stability test. The disintegration time of the GG was faster as the water temperature was increased. But disintegration time was not affected by pH on the water conditions. By using hand, spoon and power applicator, drift distances of GG were 4~5m, 7 m and 10~12 m, respectively. GG showed good herbicidal efficacy and plant safety in all of the application methods such as, using hand, spoon, power applicator and RCAA. Application times of GG, GR, SC and TB by hand in $4,000m^2$ were 38 min. 4 sec, 42 min. 20 sec, 38 min. 10 sec and 21 min. 4 sec, respectively, but application time of GG by using RCAA was 1 min 32 sec. According to appearance and characteristics of formulation types, suspension concentrate (SC) and GG were possible formulation types for RCAA.

무인헬기 살포로 논에 발생하는 잡초를 방제할 목적으로 macrogranule(GG) 제초제를 개발하였다. 약제 제조와 제조약제의 안정성, 살포방법에 따른 적용방법을 조사하였고, 제형별 살포소요시간 경제성을 분석한 결과를 요약하면 다음과 같다. 제조 GG의 입경(粒經)은 2.5~3mm 범위내에 85%이상을 차지하였고, 가비중은 $0.2\sim0.4g\;mL^{-1}$로 수면에서 부유성을 갖고 확산되는 입제고형물이었다. GG의 저장안정성은 $54{\pm}2^{\circ}C$ 항온기에서 2, 4, 6, 8주간 저장 후 halosulfuron-methyl을 HPLC로, mefenacet는 GC로 분석한 결과 유효성분 및 외형 변화가 없이 안정되어 있었다. GG의 수중붕괴성은 온도가 상승할수록 증가하였다. 또 담수 중 pH별 수중붕괴성은 담수 pH의 영향은 없었다. GG의 살포거리는 손살포, 도구살포 및 기계살포 등에서 각각 4~5m, 7m, 10~12m로 살포방법에 따라 달랐다. GG의 약효 및 작물안전성은 손살포, 도구살포, 기계살포 및 무인헬기살포에서 모두 우수하였다. 제형간 $4,000m^2$ 기준 손살포 소요시간은 GG, GR, SC, TB가 각각 38분 4초, 42분 20초, 38분 10초, 21분 4초였으나, 무인헬기 살포시 1분 32초를 나타냈다. 제형의 형태 및 특성상 무인헬기살포가 가능한 제형은 SC, GG였다.
